Abstract

A mobile device allows a letter input based on a cut or copy and paste technique. In a method for inputting a letter, the mobile device displays letters inputted by a user in a letter input window. The mobile device receives the selection of at least one of the displayed letters and the selection of a position in the letter input window. Then the mobile device moves and displays the selected at least one letter to the selected position. This letter input method is available for any types of the mobile devices regardless of being based on a touch screen or not.

Claims

1. A method for inputting a letter in a mobile device, the method comprising:

displaying letters inputted by a user in a letter input window;

selecting at least one of the displayed letters;

selecting a position in the letter input window; and

moving and displaying the selected at least one letter to the selected position.

2. The method of claim 1, further comprising:

displaying a line-like cursor in the letter input window.

3. The method of claim 2, wherein selecting at least one of the displayed letters comprises:

receiving a first touch inputted at one of the displayed letters or inputted between the displayed letters;

displaying the cursor in an input position of the first touch;

receiving a second touch inputted at the displayed cursor more than a given time;

changing the line-like cursor into a block-like cursor;

receiving a drag inputted along at least one of the displayed letters; and

finding the at least one letter in an input path of the drag.

4. The method of claim 3, wherein selecting at least one of the displayed letters comprises:

changing a graphic representation of the at least one letter found in the drag path.

5. The method of claim 2, wherein selecting at least one of the displayed letters comprises:

receiving a touch inputted at one of the displayed letters;

determining whether the touch is inputted more than a given time;

if the touch is inputted more than the given time, changing the line-like cursor into a block-like cursor;

receiving a drag inputted along at least one of the displayed letters; and

finding the at least one letter in an input path of the drag.

6. The method of claim 5, wherein selecting at least one of the displayed letters comprises:

changing a graphic representation of the at least one letter found in the drag path.

7. The method of claim 1, further comprising:

displaying a line-like cursor at the selected position; and

receiving a touch inputted at the displayed cursor.

8. The method of claim 7, wherein moving and displaying the selected at least one letter comprises:

after receiving the touch inputted at the displayed cursor, moving and displaying the selected at least one letter to the selected position.

9. The method of claim 1, wherein selecting the position comprises:

receiving a touch inputted at the selected at least one letter;

receiving a drag inputted in the letter input window; and

finding an end position of the drag.

10. The method of claim 1, wherein selecting at least one of the displayed letters comprises:

receiving a touch inputted at one of the displayed letters or inputted between the displayed letters;

receiving a drag inputted along at least one of the displayed letters;

finding the at least one letter in an input path of the drag; and

determining whether a direction of the drag is a first direction or a second direction.

11. The method of claim 10, wherein moving and displaying the selected at least one letter comprises:

if the drag direction is the first direction, cutting the selected at least one letter found in the drag path and then pasting the selected at least one letter onto the selected position; and

if the drag direction is the second direction, copying the selected at least one letter found in the drag path and then pasting the selected at least one letter onto the selected position.

12. The method of claim 2, wherein selecting at least one of the displayed letters comprises:

moving the cursor in response to a first input of a navigation key;

changing the line-like cursor into a block-like cursor in response to an input of a first key;

changing a graphic representation of at least one letter selected by the passage of the block-like cursor in response to a second input of the navigation key; and

determining the selected at least one letter as a letter to be moved or copied in response to an input of a second key.

13. The method of claim 12, wherein moving and displaying the selected at least one letter comprises:

in response to a second input of the second key, cutting or copying the selected at least one letter and then pasting the selected at least one letter onto the selected position.

14. The method of claim 12, wherein selecting at least one of the displayed letters comprises:

after the changing of graphic representation, determining whether the navigation key in the second input is a rightward key or a leftward key, and

wherein the determining of the selected at least one letter includes;

if the navigation key in the second input is the rightward key, determining the selected at least one letter as the letter to be moved; and

if the navigation key in the second input is the leftward key, determining the selected at least one letter as the letter to be copied.

15. The method of claim 2, wherein selecting at least one of the displayed letters comprises:

moving the cursor in response to a first input of a navigation key less than a first given time;

changing the line-like cursor into a block-like cursor in response to a second input of the navigation key more than the first given time;

changing a graphic representation of at least one letter selected by the passage of the block-like cursor in response to a third input of the navigation key less than a second given time;

determining the selected at least one letter as a letter to be moved or copied in response to a fourth input of the navigation key more than the second given time; and

moving the cursor to the selected position in response to a fifth input of the navigation key more than a third given time.

16. The method of claim 15, wherein moving and displaying the selected at least one letter comprises:

in response to a sixth input of the navigation key more than a fourth given time, cutting or copying the selected at least one letter and then pasting the selected at least one letter onto the selected position.

17. The method of claim 15, wherein selecting at least one of the displayed letters comprises:

after the changing of graphic representation, determining whether the navigation key in the third input is a rightward key or a leftward key, and

wherein the determining of the selected at least one letter includes;

if the navigation key in the third input is the rightward key, determining the selected at least one letter as the letter to be moved; and

if the navigation key in the third input is the leftward key, determining the selected at least one letter as the letter to be copied.

18. A mobile device comprising:

a display unit configured to display a letter input window, at least one letter and a cursor;

an input unit comprising at least one key and configured to receive user'"'"'s input instructions; and

a control unit configured to enable the display unit to display letters inputted by a user in the letter input window, to select at least one of the displayed letters through the input unit, to select a position in the letter input window through the input unit, and to enable the display unit to move and display the selected at least one letter to the selected position.

19. The mobile device of claim 18, wherein the input unit and the display unit comprise a touch screen.

20. The mobile device of claim 19, wherein the control unit is further configured to enable the touch screen to receive a first touch inputted at one of the displayed letters or inputted between the displayed letters, to display the cursor in an input position of the first touch, to receive a second touch inputted at the displayed cursor more than a given time, to change the cursor into a block-like cursor, to receive a drag inputted along at least one of the displayed letters, and to find the at least one letter in an input path of the drag.
